I'm looking for a male or female (or other) spellcaster (wizard, witch, warlock, mage, etc) RP where I'm their familiar. Details can be hammered out with my owner and I'm happy to play an anthro or nonanthro in this. The relationship will definitely involve power exchange, and I'm game for being a fertile bargaining chip with summoned elder horrors, an experimental test subject for alchemical admixtures, or a convenient vessel for magic essence.

Feel free to respond with additional ideas, even if you don't want to own your own familiar.
